The Bchecinl.. referred to in these Letters Patent and part ofthe same.

To all whom 'it may concern: l

Bc it known that I, GEORGE SHA'rswnL'n, of Wan# kegzi-n, in the county of Lake and State'of Illinois, have Ainvented an Improved Window-Screen; `and I do hereby declare thatthe following is a full and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings and letters marked thereon making a part of this description, in which-'-l Figure l is a perspective representation of a window-trame in which my improved screen is placed.

Figure 2, a horizontal section of the same. x Figure 3, an elevation of' the dowel-pins and part of the screen. 1

Thenatnre of the present invention consists in' making a window-screen in two parts, the two parts-being hinged together in the middle, and dowehpins, which fit into holes made' in the top of the lower window` f sash, and prevent the screen from swinging and-get? ting out of place. The screen. is also provided/with a hook, which holds the dowel-pius in place/in the top of said sash, as the whole is hereinafter fully dc- A represents the top and E tine sides of an ordinary windowfiarne,in which a sash and my improved screen are placed.

This screen is composed of two rectangular frames, B, which-fill the window-frame A E when. the frames are parallel to each other, and which are hinged togetheig'as shown at d, lig. 2, so that, when dow'el-pins F F, g. 3, are raised out of the top of the sash x, the screen may be readily removed from the frame( This arrangement is also such that either dowel-pin may operate as aA pivot for its respective frame to swing on, as shown by dotted lines G, ig.'2. The dowels, consequently, answer a double purpose: {irse/to hold the screen in the window-frame; second, to allow it to swing open. i

In order to secure the screen/permai'iently to the sash x, an ordinary hook and/fstaple, C, is used, as shown infig. 1. l

To fit the vertical sides of thezscreern-so as to be placed in windows whose sashes arehnrig with weights, grooves c, iig. 2,'"are vout in them,'so'as to allowthe sash-cords regu/to operate.

To pnt lle screen in a window, its middle part should be rought forward, as shown byl dotted lines Z, and then placed in the groove in which the ss/runs, and the dowel-pins F put in holes made in t ie top of sash x, after which the hook G can be pnt in its staple, and the screen will be in position.

Having thus described my invention,

Wha-t Iclaim,and desire to secure by Let-ters Patent of the UnitedStates, isv 1. A two-part window-screen,` hin/ged together in its middle part,so that it may be placed in a window and swing in it, as set forth...

2. A two-part hinged screen, provided with dowels fitting into the `sash x, as and for the purposeset forth. f
